Hello,

 

I used telerik:ReportViewer control in my application which is  developed by C# and WPF. It works well on my own computer(Windows 10), but it crashed immediately when it runs in win7. 

 

The detail info of my develop environment: Window 10 Pro (Version 1903)、 Visual Studio 2019

The detail info of my project：Telerik_UI_for_WPF_2019_1_116、Telerik_Reporting_R1_2019_13_0_19_116、.NET Framework 4.5

The detail info of my test environment: Window 7 Enterprise (x64, SP1),  .NET Framework 4.5.2 DevPack (I also tried 4.5.2 Full Version, still crashed)

 

The source code of my project is shown below. In order to find the cause of issue, there is only a report viewer control left.

 

Here is the error info when it crashed in win7(after i click the button):

 

Then I used DispatcherUnhandledException in my code to catch the exception, and find a  XamlParseException was throwed in reportviewer control. The detail info of this exception is too lang. So i attach the exception image at the end.

 

My application works well in win7 when i use telerik report 2014Q1. Not long ago, i upgraded it to 2019Q1, and then it crashed like that.

Hope for your advise. Thanks.

 

Our company has a client that uses Telerik Reporting. They are not using the Telerik Reporting service. They are using the reporting DLL and rendering the reports on their web server. This is how the ReportServiceConfiguration is initialized:

ReportServiceConfiguration = new ReportServiceConfiguration
{
    HostAppId = "Html5App",
    Storage = new FileStorage(),
    ReportResolver = new TelerikReportResolver(MDBReportHelper.GetReportTemplatesPath()),
    WorkerCount = 10
};

The application works as expected when running on a local machine (we can see an increase in pages being rendered in parallel, when we increase the workerCount property). However, the client reports that when deployed to their QA server, it generates only 2 pages at a time, no matter the value set to the workerCount property, and they would like to improve that. The configuration of their QA machine is as follows:

OS: Windows Server 2012 R2
CPU: 8 vcpu's - Intel Xeon CPU E5-2673 v4 @ 2.30GHz
RAM: 56GB

Their web app is running on a separate App Pool in IIS.

Do you know if there is any way to increase the number of pages, generated in parallel?

Hello,

I am currently trying out Telerik reporting and using.net standard for report's source, I followed the suggested ntier design of this thread https://www.telerik.com/forums/net-core-class-library-as-an-objectdatasource, passing dummy collection is easy however implementing ADO for .NET Standard returns assembly issues, do you have examples of .net standard project that uses ADO.NET?

If you try to create a task through the scheduling function of the report server, an error such as the attached image occurs.
Agent is running, and looking at the log taken by Agent, it appears as below.
Please tell me which part to check.

I want to limit table items display in per page, such as 4, I used RowNumber(), but it had no effect.

Hi,

I have a parameter that controls the visibility of page footer called "Show only page footer on the last page".

I also have a group footer on top of the page footer containing a HtmlTextBox with some custom footer texts, since the page footer can't grow during render it is placed in the group with PrintAtBottom set to true.

The group footer should also be hidden when page footer i hidden. It seems to work when i set the group footer to PrintOnEveryPage = false and when i set the GroupFooter.Visible = PageFooter.Visible inside of PageFooter_DataBound.

But,

This fails when i want to render multiple reports like 2 invoices and when the report engine renders a Empty page. Then i figured that is should control the visibilty of the "footers" by checking PageNumber = PageCount aswell but it looses the PageNumber and PageCount on this empty page. So i cant tell if it is the last page or not.

 

How to encounter this issue?

Good evening,

I'm trying to create a report with .net in MVC but the data comes from a soap WSDL, so I pass the query result to an Object Data Source in the controller and assign it to the report Viewer in the view but not displays the report.

 

  <div class="container">

            // Creating a new report

            Telerik.Reporting.TypeReportSource reportsource = new Telerik.Reporting.TypeReportSource() { TypeName = "ReportLibrary.OdioEsteProyecto, ReportLibrary" }; //
            Telerik.Reporting.ObjectDataSource datasSource = Model.ods; //this ods is a  ObjectDataSource variable who came from the model 

            if (datasSource != null)
            {
                <telerik:ReportViewer ID="MyReportViewer"
                                      ReportSource=reportsource
                                      ObjectDataSource=datasSource
                                      runat="server"
                                      High ="100%"
                                      Width="100%"
                                      DocumentMapVisible="False"
                                      ParametersAreaVisible="False"
                                      ShowDocumentMapButton="False"
                                      ShowHistoryButtons="False"
                                      ShowNavigationGroup="True"
                                      ShowParametersButton="False"
                                      ShowPrintPreviewButton="False"
                                      ShowRefreshButton="False"
                                      Skin="WebBlue"
                                      Visible="True">

                </telerik:ReportViewer>
          }

    </div>

 

HELP

Hi Team,
I am using Trial version of Telerik Reporting (v8.2). In that I am getting following issues,

1. I am binding the table data by using NeedDataSource Event. It's binding the data well, but the table is keep on repeating many times, even I am having Table in Report header page and made data source property of Report as NONE.

2. I have imported External XSLT into my report and assigned Style name to particular Header. Style is getting updated in Design time, but while running the application in browser it is not running.

Kindly clarify the details ASAP.

Regards,
Ram

Issue 1 a b

Issue 2 c d

in a crosstab.

Anyone know how to do this? :) I'm attaching screen from group explorer window.

Thanks a lot in advance.

Hi,

When generating a PDF report using the ReportProcessor from a trdx report,
is it possible to catch errors such as if a used field in the template is
not present in the dataset?

I'm using the ErrorEventHandler like this, but it is not triggered if a used field is not present in dataset.
It just renders the report anyway and leaves the label empty.

...
reportObject.Error += (innerSender, eventArgs) =>
{
    _logger.Error(eventArgs.Exception, "Error processing report PDF", reportId, parameters);
};


If you don't support it today, it would be great if I could decide, whether or not the processor should trigger the error handler in cases like this.

Cheers,
Casper
